Title: An improved means for governing the speed of internal combustion engines and the like
IPC: F02D17/00
Filed: 1919-01-18
Abstract: 141,789. Thomas, J. G. P. Jan. 18, 1919. Fluid governors; transmitting-mechanism. - An engine governor comprises a jet movable under the reaction of fluid issuing from it, means driven by the engine for pumping fluid through the jet, and means actuated by the movement of the jet for controlling the engine speed. In one form, the jet 2 is carried by a hollow arm 1 provided with a recessed boss 3 pivoted on a hollow spindle 4, which is open to the pump delivery 5. The boss 3 is connected by flexible joints on a shaft 7 to the spindle 8 of the throttle valve. On the shaft 7 is pivoted, with lost motion, the throttle pedal 10 or a lever connected to it, and pressed upwards by a spring, so that when released, the shoulders 11, 12 engage and the throttle is closed to an extent limited by a stop 17, but when pressed down, the throttle spindle follows it only so far as the governor allows. The movement of the arm 1 may be resisted by a spring or bv piston exposed to the fluid pressure and pressed upwards by a spring 16. To vary the speed at which the governor operates, a valvecontrolled by-pass may be provided between the pump and the arm 1. To compensate for leakage in the pump through thinning of the oil by increase of temperature, a constriction is provided in the passage between the pump and the arms 1, so as to provide a resistance to flow that increases rapidly with increase in the viscosity of the oil.

Abstract: 1510052 Discharge lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 Jan 1976 [17 Jan 1975] 1358/76 Heading H1D A self-stabilizing discharge lamp, having a filling mainly comprising sodium and xenon in which the pressure of the xenon in operating conditions is greater than 600 Torr and is more than twenty times greater than the pressure of the sodium vapour, is operated such that the temperature of the coldest spot in the discharge tube obtains a value of between 500 C. and 675 C., and that sodium is present in an excess. It is found that for this temperature the sodium vapour pressure is in the range 4-70 Torr and that the spectral distribution of the emitted light is similar to that of a high-pressure sodium lamp, i.e. concentrated near a wavelength of 5900 Angstrom. The required temperature of the coldest spot in the discharge tube, i.e. behind the electrodes 4, 5, may be achieved by varying the supply voltage to the lamp, modifying the interelectrode gap or distance of the electrodes from the adjacent tube walls or as shown, by providing heat shields or cooling rings 18, 19 of tantalum around the tube 3 at the coldest spot. With the particular relationship between the sodium and xenon pressures as specified the lamp operates without a ballast, but a heating member 14 is provided around the tube 3 to facilitate starting of the lamp.

Title: Process for the production of fibres, particularly spinning fibres from gramines low in silica
IPC: D01C1/04
Filed: 1939-01-11
Abstract: 523,653. Fermentation processes for obtaining fibres. THIEMANN, W. H. A. (Buhrmann's Papiergroothandel Afdeeling H. de Groot N. V., G. H.). Jan. 11, 1939, No. 1415/38. [Class 120 (i)] Fibres for spinning or papermaking are obtained from gramineµ, particularly sugar cane and bagasse, by a preliminary steeping in water to initiate separation of the parenchyma from the bast fibres, mechanical treatment such as squeezing or stamping, retting under water, and final separation of the parenchyma. In an example, bagasse is immersed for some hours in about 10 times its weight of water until it has taken up about 85-88 per cent. of its weight. The wet material is then put through a stamping machine and about 8-10 per cent. of parenchyma cells which have been loosened by the treatment are washed away by a spray of water. The remaining material is placed in a vat in which it is prevented from rising to the top and covered with a liquid containing a culture of retting bacteria. A layer of paraffin oil is floated on the top and the retting allowed to proceed for 6 to 8 days at the usual 28-30‹C. The material is again sprayed with water, when another 20 per cent. of the parenchyma cells are removed, and the remaining bast fibres pressed and heated with 1 to 1À5 per cent. of caustic soda solution. For production of high grade spun products the fibres are subjected to a " cottonizing " process consisting in treatment of the fibres while still damp withchlorine or chlorine-yielding substances or peroxides, and then removing the oxidation products with dilute alkali or alkali sulphites.
